Custom USB sticks bypassing Windows 7/8′s AutoRun protection measure going mainstream

by

When Microsoft disabled AutoRun on XP and Vista back in February, 2011, everyone thought this was game over for the bad guys who were abusing the removable media distribution/infection vector in particular. However, pragmatic and market demand-driven opportunistic cybercrime-friendly vendors quickly realized that this has opened up a new business opportunity, that is, if they ever manage to find a way to bypass Microsoft’s AutoRun protection measures. Apparently, they seem to have a found a way to bypass the protection measure by tricking Windows into thinking that the connected USB memory stick is actually a ‘Human Interface Device’ (keyboard for instance), allowing them to (physically) […]

How much does it cost to buy one thousand Russian/Eastern European based malware-infected hosts?

by

By Dancho Danchev For years, many of the primary and market-share leading ‘malware-infected hosts as a service’ providers have become used to selling exclusive access to hosts from virtually the entire World, excluding the sale and actual infection of Russian and Eastern European based hosts. This sociocultural trend was then disrupted by the Carberp gang, which started targeting Russian and Eastern European users, demonstrating that greed knows no boundaries and which ultimately led Russian and Ukrainian law enforcement to the group. What’s the probability that Russian/Eastern European cybercriminals will continue targeting their own fellow citizens in an attempt to monetize the access to their […]

by

A newly launched managed ‘HTTP-based botnet setup as a service’ aims to attract novice cybercriminals who’ve just purchased their first commercially available malware bot — or managed to obtain a cracked/leaked version of it — but still don’t have the necessary experience to operate, and most importantly, host the command and control server online.

New Mac Malware Uses Right-to-Left Override To Trick Users

by

By Michael Sweeting After a relatively long lag period without seeing any particular new and exciting Mac malware, last week we saw the surfacing of a new and interesting method of compromising the OSX system. Malware authors have taken a new approach by altering file extensions of malicious .app packages in order to trick users into thinking they are opening relatively harmless .pdf or .doc files. Changing file extensions in Mac OSX can be tricky due to a built in security feature of the OS that detects attempts to change the extension and automatically annexes the extension of its correct […]

New Rogue “Antivirus System” locks you out of safe mode

by

By Tyler Moffitt Recently we’ve seen a new fake security product running around that has made improvements to the standard rogue. Typical rogues are annoying, but relatively easy to take care of. Previously, all you had to do was boot into safe mode with networking and remove the files and registry entries (or install Webroot). Support forums everywhere use safe mode with networking as the “go to” mode for virus removal as non-core components are not loaded at start up and it’s easier to isolate problems. In the vast majority of the rogues we see, they are not loaded in […]

by

In a clear demonstration of low QA (Quality Assurance) applied to an ongoing malicious spam campaign, the cybercriminals behind the recently profiled ‘Cybercriminals spamvertise tens of thousands of fake ‘Your Booking Reservation at Westminster Hotel’ themed emails, serve malware‘ campaign, have launched yet another spam campaign. Despite the newly introduced themed attempting to trick users into thinking that they’ve received a ‘iGO4 Private Car Insurance Policy Amendment Certificate‘, the cybercriminals behind it didn’t change the malicious binary from the previous campaign.

New commercially available mass FTP-based proxy-supporting doorway/malicious script uploading application spotted in the wild

by

For many years now, cybercriminals have been efficiency abusing both legitimate compromised and automatically registered FTP accounts (using CAPTCHA outsourcing) in an attempt to monetize the process by uploading cybercrime-friendly ‘doorways’ or plain simple malicious scripts to be used later on in their campaigns. This practice led to the emergence of DIY (do-it-yourself) tools and managed service platforms that allow virtually anyone to start monetizing these fraudulently or automatically registered accounting data, signaling a trend towards an efficiency-driven cybercrime ecosystem – a concept that’s been materializing on a daily basis for a couple of years. In this post, I’ll profile a desktop-based tool that allows cybercriminals […]
